Growing up my folks and every one older that I knew discouraged my brothers and I from shaking or taking things from people with our left hands . Even my kids brother who is a south paw learned to use his right hand when shaking people or taking things from them.

Over two decades later, it's so common to see people take things from you or proffer their left hands for a handshake even when you have your right hand pointing at them irrespective of whether or not you're older, richer or more senior to them in the office.

Is this some new trend or it really doesn't make a difference which hand you use?

^^îf people still clean their nyansh with water, and using their left hand to do so, then i think people should continue NOT using their left for contact to others etc
